=head1 INTRODUCTION

Perl module for TrueType/OpenType font hacking. Supports reading, processing and

writing of the following tables: GDEF, GPOS, GSUB, LTSH, OS/2, PCLT,

bsln, cmap, cvt, fdsc, feat, fpgm, glyf, hdmx, head, hhea, hmtx, kern,

loca, maxp, mort, name, post, prep, prop, vhea, vmtx and the reading and

writing of all other table types.

In short, you can do almost anything with a standard TrueType font with

this module. Be Brave!

Any suggestions, improvements, additions, subclasses, etc. would be gratefully

received and probably included in a future release. Please send them to me.

This module has been tested on Win32, Unix and Mac.

Applications that were associated with this module have been moved to

Font::TTF::Scripts where great things can be done.

=head1 SYNOPSIS

Here is the regression test (you provide your own font). Run it once and then

again on the output of the first run. There should be no differences between

the outputs of the two runs.

    use Font::TTF::Font;

    $f = Font::TTF::Font->open($ARGV[0]);

    # force a read of all the tables

    $f->tables_do(sub { $_[0]->read; });

    # force read of all glyphs (use read_dat to use lots of memory!)

    # $f->{'loca'}->glyphs_do(sub { $_[0]->read; });

    $f->{'loca'}->glyphs_do(sub { $_[0]->read_dat; });

    # NB. no need to $g->update since $_[0]->{'glyf'}->out will do it for us

    $f->out($ARGV[1]);

    $f->DESTROY;               # forces close of $in and maybe memory reclaim!

=head1 INSTALLATION

If you have received this package as part of an Activestate PPM style .zip file

then type

    ppm install Font-TTF.ppd

Otherwise.

To configure this module, cd to the directory that contains this README file

and type the following.

    perl Makefile.PL

Alternatively, if you plan to install Font::TTF somewhere other than

your system's perl library directory. You can type something like this:

    perl Makefile.PL PREFIX=/home/me/perl INSTALLDIRS=perl

Then to build you run make.

    make

If you have write access to the perl library directories, you may then

install by typing:

    make install

To tidy up, type:

    make realclean

Windows users should use dmake instead of make.
